THEODORE F. HUSSA, OF MONTGLAIR, NEW JERSEY.

To all whom it may concern:

Be it-knownthat IYTHEODORE It IIussA, aocitizenjof the United States,residing at Montclair, in thercounty ofEssexcand State of NewJersey,have. invented certain new .and-useful .-Iinproyements in Elements forSingeingxApparatus, of whichthe following. is a spe'oification,reference being had therein. tov the .-.accompanying drawings, 10"

which format part-thereof.

- In singeingapparatus. used in the textile art, it is acommon practiceto pass ind v dual threads on fabric, inclose juxtaposition to[t::fl3-1Illllg .element to remove the: fluff therefrom; In some. typesof such apparatus-, the element. lconsists of suitable gas burners,:while in other types, platinum elements-brought to an incandescentstate by -bei ng included in anz-electrical circuit, are employed Withtheluse of elements of the latter type, it is customary to cause acurrent of air to pass about the element to remove, theflnfi' or preventits accumulating upon .the element itself.

5 Platinumelementsare .not only expensive to produce by reasonofthequantity of the metal necessarily incorporated in the element, butthe renewal of these elements as the result of deterioration fromcontinued use makes the upkeep of the apparatus expensive.

In view of these conditions there has been a persistent efiort toproduce elements of metal other than platinum which may be brought tothe desired state of incandescence to properly singethe threads orfabric, with an economy in current consumption which will make their useas a substitute for plati-' fabric being treated.

The invention consists primarily in an element for singeing apparatusconsisting of an alloy of nickel and chromlum adapted to be readilybrought to an incandescent Specification of Letters Patent.

state; and in such other novelcharacteristics as are hereinafter setforth andydescribed and more part1cularly pointed out 111'lJl1G I claimshereto appended.

Referring to the drawings I -Figure 1 is aside view, partly in section,of an elementfor use insingeingthreads; and

Fig. 2 is a perspecti'veview of an-element for use in singeing-fabrics.

FLike letters refer .to like parts in both views.

In the" embodiment of my invention shown in F ig. 1 of the drawings, aindicates a troughed section adjacent which the thread ispassed inremoving fiufftherefrom." This element is provided at one end thereofwith an lBXtBllSlOIl Z) adapted to be connected with one. electricalterminal, whichextension pro ects at substantlally right anglesto thetrough aand is-substantially straight. At

the other end of said trough is all-extension expansion and contractionof;,the-trough a and avo1d', the, bulging of the trough while in use.

In the form of the invention shown in Fig. 2, the construction is asheretofore described, with the exception that instead of employing atrough a, I employ an arched plate 6,

this form of the invention being adapted for use in singeing fabric.

In both forms of the invention, the portion of the elements adjacentwhich the thread or fabric passes, and also preferably the extensionsfor connecting this portion with the electrical current, is made of analloy of nickel and chromium which I have found in practice to be highlysatisfactory in an element of this character.

This alloy, I have found, becomes incandescent with a voltagesufiiciently low to permit the use in the apparatus of a number ofelements connected in series in an ordinary lighting circuit. There isno tend ency toward oxidation, and the repeated expansion andcontraction thereof does not result in molecular disturbances resultingin heat checking, or the discharge of small particles of the metal whenit is brought to incandescence.

I have found that the addition ot other metals to the alloy, such asiron, makes the alloy unsuitable for use as an element for singeingapparatus, it being necessary to use only commercially pure nickel andcommercially pure chromium in order to provide an element which may beused .tor the purpose intended. The thickness of the extensions 7) and cof the element is such as to offer little or no resistance to theexpansion of the trough portion a, or the arched por tion 0.

iVhile the voltage required to bring an element made in accordance withmy invention to incandescencc is somewhat higher than with a platinumelement, the amperage is lower. The current consumption, however, issomewhat higher with an element made in accordance with my inventionthan with a platinum element, but the difference does not exceed 20% andthe additional expense of operation is not sutiiciently great toovercome other advantages, such as the original cost of installation andthe reduced cost of upkeep as compared with a platinum element.

I am aware that an alloy consisting of chromium and nickel alone, orwith other metals, is well known in the metallurgical art, but I believethat I am the first to discover that the use of an alloy consisting onlyof chromium and nickel in an element for a singeing apparatus, impartsto said apparatus characteristics highly desirable in securing aneffective singeing of threads or fabric.

It is not my intention to limit the invention to the particularstructural character istics shown in the accompanying drawings,

it being apparent that such may be varied without departing from thespirit and scope of the invention.

Having described the invention what I claim. as new and desire to haveprotected by Letters Patent is 1. An element for singeing apparatusconsisting of an alloy of nickel and chromium adapted to be readilybrought to an incandescent state.

2. An element for singeing apparatus consisting of a portion adapted toact upon the material to be singed, integral extensions at the oppositesides thereot projecting at substantially right angles thereto, one ofsaid extensions having an inturncd portion extending substantiallyparallel with the portion operative upon the mate rial, said elementbeing formed of an alloy of nickel and chromium adapted to be readilybrought to an incandescent state.

3. An element for'singeing apparatus consisting of a trough sectionhaving integral extensions at opposite ends thereof projecting atsubstantially right angles thereto, one of said extensions beinginturned and projecting substantially parallel with said trough, saidtrough and said extension being, formed of an alloy of nickel andchromium adapted to be readily brought to an incandescent state.

In witness whereof, I hereunto all'ix my signature. in the presence oftwo subscribing witnesses. this 19th day of December, 1917.
